To all whom it may concern:

Be it known thatI, LOUIS S. FR'APPIER, a

- citizen of the United States of America, and

Reels; tion, such as will residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in enable those skilled in the artfto which it appertains to make and use thesame L i I fl This invention-relates to moving picture apparatus, whatiis known as the take-up reels 'whereon the filmis wound after projection, although I. do not confine myself to such use of my invention.

Inprojectors of modern construction the film ismoved intermittently across the aperture by means of suitable mechanism, suc

as sprockets or the like, after which it is actuated steadily by constantly moving means, a loop of film being maintained between said means, normally, to prevent any strain. on the film wb ich might cause 1t to tear, but it often happens that the'film slips at the constantly moving sprockets because of the ,joint between film sections being thicker than the film proper, or for other causes, the take-up reels then causing the' loop otiilm to be taken up instantly with the result that, when the constantly moving sprockets again, engage'the film, there is no loop between the intermittently moving means and the con'stantly moving means and thejlatter tears the film. It is the. practice now. when such tears occur, to stop the pro jeetor"operation, draw down enough film,

(manual y, to encircle the take-up reel several times, this being accomplished .by in- "sertingthe fingers carrying the torn end of the filth between the cheeksot' the reel,

arranging the saidend on the reel, and then revolving the latter several. tunes until a suffic ent strain is exerted on the film to again draw the. same from the constantly moving means but sufficient film is permittedjto; remain between the intermittent and constant means to again "form the loop referred t(i,;a n d my invention was designed to overcome this/lengthly and arduous operation of engaging the film with the reel,

. either originally or after a. tear.

invention is fully described in the following specification, of which the accompanying drawings form a part, in which of which the following is a spec1fica-' with particular reference to responding slot 1 the separate parts are designated by the same reference characters in each of the views, and in which Figure 1 is a central section taken through a reel of conventional type and showing my invention therein in the step of rengaging a torn filmwith the reel; Fig. 2 is a transverse section on the line 2-2 of Fig. 1; Fig. 8 is a. section on the line 3-3 of Fig. 2; and Fig. 4 is an inner end view of my invention removed from the reel.

In the drawings forming a part of this application I have shown a take-up reel comprising the central, circular, spool a and side cheeks a and a each of which I provide with one or more radial slots 2') in pairs, only one pair being shown, and the said.

slots being directly opposite each other in each pair, and, while conventional reels are now provided with a spring-frictional, clip for the original engagement with the film, I have not shown the same as it forms no part of my invention and may or may not be provided. a

The present form of embodiment of my invention consists of a longitudinally split pin 0, the split being shown at and the tines ot' the fork so formed are sufiiciently close to each other to insure a frictional enga e ment of the film therebetween, and I pre er to flare the outer end of the slot so formed to guide the film between the tines, as shown at 0 the pin ,0 being of slightly smaller diameter than the width of the slots 1; in which it rests or moves. The pine is provided with a handle-c andwith a fixed plate 0 closely adjacent the inner end of the slot 0 said plate being of a width in one direction of slightly less dimension than the width of the slots 1), and being of a length greatly exceeding the width of the said slots, whereby the pin may be withdrawn from the reel'in one position of said plate a and not in a position at right angles to said first-position.

Arranged slidably on the pin 0; between 9 the handle and the platen is a disk (1 of a diameter approximating. the length of the plate 0 a coil spring d bein interposed between said disk and the ban is whereby the disk is normally held against the plate 0 this beingtoinsure a frictional engagement of one of the checks of the reel therebetween in any position along the length of the, cor- If a break should occur in the film during projection of the pictures thereon, the torn end not in engagement with the reel is drawn downwardly sufficiently far to provide, the loop already referred to, the pin inserted into the slot 6 of the outer cheek 01 adjacent the periphery of the cheek, and

the end of the film passed between the tines of the pin fork until it reaches the inner end of the split therebetween, the film being between the cheeks of the reel, after which the pin is moved inwardly along the slots 71 to a position adjacent the wound portion of the film, the film being shown at e, the end at c and the woundportion at e. In this operation the plate 0 has been arranged longitudinally of the slot 7) in, which it is sliding but, when a desired position of the pin is reacherhthe handle is forced inwardly against the action of the spring, thusv moving the plate a out of the'slot 7), at which time the handle and pin are rotated through approximately ninety degrees of a circle and the handle released, the plate now being arranged transversely of the slot]; and the device is frictionally locked on the cheek a with the film end frictionally held in the split of the pin under sufiicient tension to insure film movement and the renewal of projector operation begins, this relin- "gagement of the film end not requiring more than a fraction of a, second, and, as soon as the reel has been revolved several times, the film is held: thereon by the friction of the turns around the spool a and the pin may be removed by merely rotating through an arc of a circle sufiiciently great to bring the plate in line with the slot 7) and withdrawing the entire device,

ready for another break in the film.

My device may also be used at the beginning of the film length, in the same man ner as already described, in which event I prefer to continue the slots 7) inwardly and groove the spool a, as indicated by, dotted lines in Fig. 1, at 6 in order to bury, or 1 partially bury, the pin whereby the film windsdir'ectly on the spool without binding the pin which may be instantly withdrawn 'for continuing projection, in the event of a break in the film, in themanner stated.

While I have shown one form of. embodiment, for accomplishing the desired result of instant renewal of projection in the event of a break in the film, other forms may be devised which might be in permanent but slidable connection with the film and, furtheryalthough I haveelected in the present a showing to frictionally engage the film end between the tension forks of the .pin 0, I

may dispense with this and lay the torn end of the film directly on the spool 11 or on' the film wound thereon, and then move my device against said" torn end on the spool andv hold it there in the manner already set forth, or in any other manner,

provided that the film endwas frictionally held by the pin, -either against the spool or otherwise. 1

, My device is very simple in construction and use, is'very inexpensive,and avoids the very annoying delays occasioned by a break in the film, and it may also be employed im the circles or other openings in reel cheeks alwaysprovided for lightness and to for providing the slots 7), but I preferto provide the reels already adapted for use with theparticular form of film holding pin which Imarket. 1

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

ccess to the film, without the necessity 1. The'combination with a film reel, of

a device provided with: means for engagement with the end of afilm section and means affording provision for connection to the'reel at different distances from the hub,

said film engagement means being adapted for. disconnection from one film portmn wound upon the reel and connectionwith another film portion whereby the latter may be wound on'the tormerQ U 2. The combination with a film reel, of a device provided with means for" engagement with the end ofa film section and means for connection to the reel, said film engagement means being adapted for disconnection from one film portion wound upon the reel and connection with another film portion whereby the latter may be wound on the end of a strip of film,,and means for bolding said pin in desired position on said reel, radially thereof, said device I being adapted to be removed from engagement with one part of the film wound upon the reel and be secured to the reel at a, different distance from the hub to engage the film, whereby a separate film portion may be wound on a preceding portion.

5. The combination of a film reel provided with radial slots'in the sides thereof, of a device having; means for positive engagement with the end of a film, and means for conilectingsaid device with said reel at any desired point along one of said slots, said deyice being adapted to be removed Ill l'ronrengagement with one part of the film wound iipon'thereel and bese'cured to the reel at a' different distance from the hub to engage the film, whereby asepa'rated film portion may tlon. i

6. Inicombin'ation with a device adapted for detachable connection with the end of a film portion, of a reel provided with an opening in the side thereof for the Passage of said device and wherein said device is ajdjust'a'bly held, said device being'fidapted 1 to be removed from engagement with one part of the film wound upon the reel and be Wound on a preceding per- 1 14th day of April, 1913.
